Title: Method and apparatus for degassing liquid sulfur
Inventor: LOUIE JAMES G
IPC: B01D53/52
Filed: 2004-05-18
Abstract: A vessel is mounted external to a liquid sulfur storage pit for degassing liquid sulfur at atmospheric pressure. Liquid sulfur is re-circulated from the pit to a static mixing device extending from a head space to the liquid sulfur which provides intimate contact of the liquid sulfur as it flows downwardly and sweep air flowing through the head space above the pit. Further, the static mixing device prevents free fall of liquid sulfur and the hazards of static electricity associated therewith. Use of a heat traced gas outlet induces flow of sweep gas from the system, obviating the need for a steam eductor or blower.

Title: Process for purifying an organic acid
Inventor: HEIDEL DAVID
IPC: C07C51/48
Filed: 2002-12-11
Abstract: A process is disclosed for purifying an aqueous feed stream (10) comtaining a product organic acid and a strong contaminant such as another organic acid.  The molar concentration of the organic acid in the feed stream (10) is at least 20 times greater than that of the contaminant. The feed stream (10) is contacted with an immiscible basic extractant (18) that has a greater affinity for the contaminant and which complexes with the contaminant and some of the organic acid. The complexed extractant is separated from the aqueous stream (10), so as to produce a first effluent stream (20) comprising product organic acid. The complexed extractant is contacted with a displacing acid, for which the extractant has a greater affinity than contaminant or extractant. As a result, a second effluent stream (28) comprising organic acid and a third effluent stream (30) are produced.

Abstract: A method for determining formation fluid pressure in earth formation surrounding a borehole wall uses a downhole probe coupled to a variable-volume cavity. The probe is driven into contact with formation at the borehole wall. The method includes expanding the volume of the cavity during a first period of time to establish fluid communication between tool fluid and formation fluid, by withdrawing a minimal amount of fluid from the formation. During a second period of time the tool pressure is allowed to equilibrate to formation pressure. When pressure equilibrium is established, formation fluid pressure is set equal to tool pressure. A preferred embodiment includes terminating expanding the volume of the cavity on detecting a break in the mud cake seal. An associated formation pressure tester tool includes an elongated body; a probe defining a formation fluid inflow aperture, an electromechanical assembly defining a variable-volume cavity, a pretest flow line coupling the aperture to the cavity, a pressure sensor coupled to the cavity; and downhole electronic means for controlling the expansion of the volume of the cavity.

Title: Microorganism-resistant humidifier
Inventor: KOHN GABRIEL S
IPC: F24F6/04
Filed: 2004-09-02
Abstract: A humidifier has a first sealable reservoir feeding water to a second reservoir communicating with ambient atmosphere. A blower is adapted to blow a stream of air through the humidifier to ambient atmosphere, such that the stream of air picks up water vapor from any water that may be in the second reservoir. A feeder valve feeds a quickly-evaporable quantity of water from the first reservoir into the second reservoir. The quickly-evaporable quantity of water in the second reservoir is substantially smaller than the water capacity of the first reservoir. A dry-out mechanism shuts off the feeder valve upon a user command and continues to run the blower at least until the quickly-evaporable quantity of water has evaporated to an extent effective in inhibiting the growth of microorganisms in the microorganism-vulnerable reservoir.
